This paper applies the concept of bionics to digital life and utilizes bionics techniques to mimic the characteristics of creatures so as meet the demand of facility digitalized in all aspects of life. The paper proposes a bio-robotic plant system (BRPS), which can mimic the process of plant growth and combine sensor, photo-transistors and additional light source to mimic the behavior of plant phototropism. The criteria of this system is that BRPS initiates its growth and completes flowering process upon the proximity of humans and also the contact of light source. Then, four micro photo-transistors on the mosaic are utilized to receive the light source from four directions and microcontroller are adopted to detect each direction of light and select the maximum direction of light, where the flower moves towards finally. It is verified through simulation and experiment result that the growth of BRPS varies with the time of light contact upon the proximity of humans and abundant light. When the plant flowers, it turns towards the desired direction of light correctly. The system can improve the quality of human life, lead to the balance between body and mind and is also educational.
